Product Density and Durometer Shore Hardness

What do we mean when we say soft, low, medium, high, and hard density? Those terms are subjective and vary from industry to industry. This is why it is helpful to use the Density chart and Durometer measure of the Shore Hardness Scale. Below are common materials of Presbond and comparable Shore hardness materials that may be in your everyday life.
